Abstract

광에 의한 입력상을 광전효과에 의해 투영상으로 변환하는 화상표시장치에 있어서, 화상전사수단의 크기를 감소시킴으로써 장치전체를 소형화, 저가격화를 실현할 수 있다.In an image display apparatus for converting an input image by light into a projection image by a photoelectric effect, the overall size of the apparatus can be reduced and the price can be reduced by reducing the size of the image transfer means.

복수의 굴절률분포형렌즈는 광축과 평행하게 배열하고 화상전사소자는 화상표시소자상의 광에 의한 입력상이 전기광학소자의 광고전층상으로 등배전사되도록 전기광학소자와 화상표시소자사이에 설치한다.A plurality of refractive index distribution lenses are arranged in parallel with the optical axis, and the image transfer element is provided between the electro-optical element and the image display element such that the input image by the light on the image display element is equally transferred onto the advertisement layer of the electro-optical element.

화상전사거리는 현저하게 감소될 수 있고 화상은 화질의 열화없이 전사될 수 있으므로 장치전체를 화질의 열화 없이 소형화, 저가격화시킬 수 있다.Since the image transfer distance can be significantly reduced and the image can be transferred without deterioration of image quality, the entire apparatus can be miniaturized and reduced in price without deterioration of image quality.
